Method and apparatus for controlling touch screen of terminal, and terminal

An apparatus for controlling a touch screen of a terminal, comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the processor to:
• detect a multi-touch event performed on a touch screen of a terminal, the multi-touch event being an event of generating multiple touch operations at different positions of the touch screen simultaneously, wherein the touch screen of the terminal is configured for displaying information;
• determine an area where multiple touch points corresponding to the multi-touch event are distributed, wherein the touch screen of the terminal, which is configured for displaying information, is divided into a wrong-trigger prevention area in which information can be displayed, a buffer area and a normal touch area, the buffer area being located between the wrong-trigger prevention area in which information can be displayed and the normal touch area, and the buffer area being an area formed by extending an inner edge of the wrong-trigger prevention area inward for a set number of pixel points;
• control, when all of the multiple touch points are distributed in the wrong-trigger prevention area in which information can be displayed, the touch screen to respond to a touch operation at the multiple touch points;
• control, when the multiple touch points are distributed in the wrong-trigger prevention area and the buffer area, the touch screen to always respond to a touch operation at the multiple touch points;
• and
• control, when the multiple touch points are simultaneously distributed in the wrong-trigger prevention area and the normal touch area, the touch screen not to respond to a touch operation at the touch points in the wrong-trigger prevention area, and to respond to a touch operation at the touch points in the normal touch area so as to achieve wrong-trigger prevention.
